Class: moodle_url - X-Ref
Class for creating and manipulating urls.It can be used in moodle pages where config.php has been included without any further includes.
It is useful for manipulating urls with long lists of params.
One situation where it will be useful is a page which links to itself to perform various actions
and / or to process form data. A moodle_url object :
can be created for a page to refer to itself with all the proper get params being passed from page call to
page call and methods can be used to output a url including all the params, optionally adding and overriding
params and can also be used to
- output the url without any get params
- and output the params as hidden fields to be output within a form
| __construct($url, array $params = null, $anchor = null) X-Ref |
| Create new instance of moodle_url. param: moodle_url|string $url - moodle_url means make a copy of another param: array $params these params override current params or add new param: string $anchor The anchor to use as part of the URL if there is one. |
